Wastes from a local iron and steel factory are the subject of this study The manufacturing operations in the plant under consideration are agglomeration of iron ore and sintering pig iron manufacture steel making rolling mill operations and pickling
In steel manufacturing various solid wastes are generated in wastewater treatment Iron carbon and fluxes CaO and MgO are the main beneficial components in these solid wastes for recycling in the ironmaking and steelmaking process However the wastewater treatment solid wastes often also contain some undesirable components
Recycling iron and steel Steel has one outstanding characteristic it can be endlessly recycled without its material qualities being compromised The iron atoms are indestructible and by melting scrap metal it is simple to get the atoms to arrange themselves in a new regular way to form new steel
Steel is manufactured by the chemical reduction of iron ore using an integrated steel manufacturing process or a direct reduction process In the conventional integrated steel manufacturing process the iron from the blast furnace is converted to steel in a basic oxygen furnace BOF
